Why is Tiktaalik a transitional form?

Tiktaalik roseae has features of the skull, neck, ribs and appendages that are shared with the earliest limbed animals (tetrapods), as well as fishlike features such as scales and fin rays. This mosaic of features makes it a textbook example of a transitional fossil, say paleontologists.

What are the 4 fossil types?

Was Archaeopteryx a theropod?
